SPECIFICATION formingpart of Letters Patent No. 233,193, dated October12, 1880.

Application filed January 28, 1880.

To all whom it may concern.-

Be it known that we, GEORGE B. BOOMER, of Mexico, Oswego county, NewYork, and RUFUS E. BOSCHERT, of Syracuse, Onondaga 5 county, New York,have jointly invented a new and useful Improvement in Presses, of whichthe following is a full, clear, and exact description, reference beinghad to the accompanying drawings, in which- '10 Figure 1 is a top-planview of the bed and foundation of the press, showing the rollers inposition. Fig.2 is a cross-section of the same and the platform.

Similar letters of reference indicate corre- I 5 sponding parts.

This invention relates to presses in which what is called a doublemovable platform is used, which is mounted upon trucks or wheelstraversing tracks on opposite sides of 2o the press-bed.

It consists of the employment of intermediary rollers mounted uponuprights, one or more of such rollers being located on each side of thepress-bed for the purpose of supporting z 5 the central portion of theplatform and preventing its sagging, as well as to assist in theshifting of the platform endwise.

A is the bed of the press. B is the foundation of the press, which maybethe floor of the building. 0 is the platform, mounted upon the trucks orwheels d d, which traverse the tracks 6 e and operate together in theendwise movement of the platform. E E are the rollers, which are mountedhorizontally in bearings upon the upper ends of the uprights m m, whichare so erected upon the foundation that the rollers will lie, one ormore, on each side of the bed A, parallel to it and to each other, andof such height that the platform 0 will rest upon them, the wheels d dbeing upon the tracks 0 e. The length of these rollers is designed to beabout the same as the distance between the tracks; but the length can bevaried, and also their size.

In operation these rollers serve to support 5 the center of the platformcrosswise, prevent its sagging in the center when loaded at either orboth ends, and also act as central stationary trucks when the platformis being shifted endwise Having thus described our device, what we claimis The combination, in a press, of the intermediary crosswisesupportingrollers E E, mounted in bearings on the uprights m m, with themovable platform 0, mounted upon wheels d, traversing the tracks e, whenconstructed and operating together, substantially as and for thepurposes above set forth.
